# VACUUM STRUCTURE, LORENTZ SYMMETRY AND SUPERLUMINAL PARTICLES (I)

If textbook Lorentz invariance is actually a property of the equations describing a sector of the excitations of vacuum above some critical distance scale, several sectors of matter with different critical speeds in vacuum can coexist and an absolute rest frame (the vacuum rest frame) may exist without contradicting the apparent Lorentz invariance felt by ”ordinary” particles (particles with critical speed in vacuum equal to c , the speed of light). Sectorial Lorentz invariance, reflected by…
